Lann-LAMP.

g Specication of Letters PatentNo. 13,170, dated July 3, 1855.

To all 'whom/it may concern:

Be it known that I, JAMES D. HAYS, of Mount Morris, in the county ofOgle and State of Illinois,have invent-ed anew and Improved Lamp forBurning Lard; and I do hereby declare that the following is a full,clear, andexact description of the same,

` the combination of a cylindrical chamber, l piston, and valve,arranged as will be presently shown. y

A represents the base `of the lamp to `which a cylindrical chamber B isattached,

said chamber B having a wick tube C at- Fig. l. The lower endof the wicktube O is provided with alvalve D opening upward,` `and the chamber Bhas a piston VE fitted within it said pistonf being attached to a' shaftor aXisF which passes through the center of the chamber, the edge of thepiston bearing lightly against the inner surface of the chamber B. `To:`the outer end of the shaft or axis Fa alever G is att-ached as shown bydotted lines Fig.' l.

H is the clamp 1n which the `wick is secured, said clamp being fittedwithin the wick tube C, as shown inFig. l, this clamp the wick issecured or held, these plates are perforated with holes or apertures(a), see Figs. l and 2.

The piston E is moved back till its edge reaches the wick tube C, andthe lard is then placed within the cylinder B through an opening (b) atits top. The piston E is then turned by operating the lever Gr and thelard is pressed upward within the wick tube C, raising the valve D. Theflame therefore is supplied with lard which may be put in the chamber Bin a cold state as it is immediately melted by the flame in consequenceof being forced close to it by the piston. The holes or apertures (a)cause the flame to be brilliant and they afford a free communication ofthe lard to the wick causing the lamp to burn a considerable timewithout operating the piston, as the lard will be in contact with thewick as far up as the holes or apertures (a) extend,

the lard in the wick tube when the piston is JAMES D. HAYS.
